Effective duration can be measured differently by different analytics tools used by Nuveen or the fund sub-adviser. The effective duration measures presented here may differ from those used by portfolio teams to manage the portfolios, or in other presentations describing these portfolios. Also, this effective duration measure may differ from that used by other fund sponsors, so effective durations of funds in different fund complexes may not be directly comparable.

Call Exposure*

Percentages reflect the percentage of the fund’s investment exposure callable in the timeframe relative to the “as of” date shown. The "Next 12 months" figure (if shown) includes investments that are currently callable, as well as callable in the next 12 months.

Securities subject to call may not be called.

Credit Quality*

As of 01/31/2018

Exposures and breakdowns are asset-weighted using the current market value of bonds held in the portfolio, as well as the full amount and exposure of bonds held in a tender option bond (TOB) trust, even though the fund owns only the residual inverse floater in its portfolio and managed assets.

This may not be fully consistent with generally accepted accounting principles.
